SPECIFICATION forming part of Letters Patent No. 301,013, dated J'une24:, 1884.

Application filed October 3, 1883.

To ELZZ whom it may concern:

Be it known that we, WILLIAM N. SHARP- NACK and MIcHAnL lVIOMAHON,citizens of the United States, residing at Bucyrus, in the o enableothers skilled in the art to which it ap-- pertains to make and use thesame.

The object of our invention is to improve separators and smutters. Ourinvention therefore consists of the construction and combina- 1 tions ofparts, all as will hereinafter be described in the specification,andpointed out in the claims, reference being had to the accompanyingdrawings, in which Figure 1 represents a perspective of the machine;Fig. 2, a vertical section through the separator on line 00 m, Fig. 3;Fig. 3, a vertical section through the smutter and separator on line yy, Fig. 2; Fig. 4, a detail showing the equalizingwalve in perspective;Fig. 5, a

section on line 00 a", Fig. 3; Fig. 6, a detail in section showing theconnection between spout D and the smutter-cylinder; Fig. 7, a

detail showing the connection between the smutter-cylinder and chamberE.

The brushes shown in Fig. 3 are not shown in Figs. 6 and 7, as it isimmaterial to this invention what means are used in the smutter forcleaning the grain.

A represents the case, which incloses the 3 5 several parts of theseparating device, and is closed on all sides, except at pointshereinafter described. The top is closed by hopper B, placedbeneath theriddle B, which may be of the usual form, and provided with the usualpitman, S, suitably connected for converting motion. The part S isconnected by belt S with shaft F", having pulley F*, which is connectedwith any suitable power in the usual way. From the hopper B extend 5spouts I), only one of which is shown, which ing an inclined bottom, I),and dischargeopening I), which leads to a separating-chamber, O, havingan inclined perforated bottom, 0. The upper part, c, of this chamber ispreferably curved, and has an opening, o which described.

open into a receiving chamber, B hav (No model.)

connects the chamber 0 with the interior of the case,for a purpose whichwill presently be The grain from chamber B falls upon the inclinedperforated bottom 0, and passes to a passage, .D, which communicateswith chamber 0 by an opening, d, and leads to the smutter, as shown inFig. 6. The grain in the smutting-cylinder is gradually worked to theopposite end of the cylinder, and enters the head G", which is connectedwith chamber E by passage E, through which the grain is projected by thebeaters when they come opposite to the passage E, as shown in Fig. 7.Said chamber E is provided with an inclined bottom, 0, and an opening,0, which connects it with a separating-chamber, E constructed insubstantially the same manner as chamber O- that is to say, it isprovided with an inclined perforated bottom, 6 a curved upper part, 6having an opening, c", which connects the chamber E with the interior ofthe case, and a discharge-opening, c", connecting it with a passage, E,which leads from the machine. The perforated bottom e, as well as thebottom 0, connect their respective chambers with the outer air.

WVithin. the case A is a fan-case, F, open at both ends f, and providedwith a fan, F, mounted on a shaft, F, journaled in any suitable manner,and extending outside the case, the extension thereof having the usualpulleys thereon. The fan-case is also provided with a discharge-spout, Fwhich leads to the dustroom. In front of the fan is an extension, A, ofthe case A for the smutter-cylinder G, which is connected with theinterior of the case by a passage, A. The spout extends verticallythrough and divides this passage A into two parts, as shown in Figs. 3and By locating the fan-case within the case A and having the formeropen at both ends, the air and dust are drawn from the case with bettereffect, as no conflicting currents will be generated. Thesmutter-cylinder is mounted 'on the extension and provided with beatersand brushes 9 and T. The front part of the cylinder abuts against thecross beam The rear beam, A, is provided with a longitudinal slot, a,which forms a continuation of the passage G, formed by the cover G,which incloses the top of the cylinder. This cover the case throughopenings 0 and e.

G is attached by one end to the rear beam, A, and extends over to thewall A of the extension A, to form an air-passage, a, between it and thetop beam, The ends of the cover are inclosed between the vertical wallsa, which are formed with or attached to the extension A. In the wall Abelow the passage a is formed a second passage, a, provided with a dooror valve, a, for regulating the admission of air to the extension A. Thecylinder G is interposed between the fan and the front wall, A, which isprovided with the passages a and a. WVhen the fan is revolved, the airis sucked in-through said passages. The air entering bypassage a passesabove and around the cylinder to the passage A and that enteringby'opening a passes beneath the cylinder, both serving to clear the dustand smut from the latter for the fan to draw away. The fan also actsupon the grain in separating-chambers G and E by drawing air from theperforated bottoms c and 0 into It will be noted that the air is drawnin at the point where the grain is scattered by falling from theinclined bottoms of chambers TB and E. The refuse will thusbe readilyseparated from the good grain. It happens now and then that one of thechambers l3 or E becomes clogged with grain. The suction through theunclogged passage will therefore be greater than that through theclogged passage. To overcome this objection an equalizing-valve, I, issuspended in the case between the openings c and 0'', so that when thesuction is equal in the chambers G and E the valve will remainstationary or in its normal position; but if the suction becomes greaterin one chamber than in the other the equilibrium of the valve will bedestroyed by the air drawing upon one side of the valve. In such a casethe valve will be drawn or tilted by the unequal suction toward andclose the opening through which there is the greatest suction, thusleaving the full force of the fan to act upon the clogged passage untilrelieved, when the valvewill assume its normal position. One means forcarrying this object into ef feet is shown in the accompanying drawings.The valve I is wedgeshaped, the journal,

which has bearings in the case, being at the angle. The ends of thewings of this valve are provided with vertical pieces 6, adapted toclose the openings 0 and c. If desired, a Weight may be attached at theangle of the valve to retain it in a vertical or its normal position.The refuse drawn through openings 0 and 0 falls upon inclined plates orshelves M, arranged in the case between the fan-caso and the openings 0and 0". As the refuse passes from the upper shelves to the lower, thedust and lighter particles are drawn through the spaces between them andinto the fan-case, and the screenings pass into the hopper N, which hasa spout, a, passing through the passage A- and the bottom of the case.Byhaving the fan-case open at both ends the refuse will fall evenly uponthe shelves, and the dust will be more thoroughly separated from thescreenings, and by placing the fan-case so that the ends of the case andthe ends of the shelves are parallel the best result will be produced.

The operation of the machine is as follows: Grain is fed upon the riddleto be cleaned of straw and other large refuse, which pass off at thelower end. hopper B, and passes through spouts b, chamber 1-3 andpassage b to the separating-chamber C, where the refuse is partly orwholly removed by the air sucked through the perforated plate 0 andchamber 0, as the grain falls upon the former from the chamber B Thecleansed grain passes through passage D to one end of the smutter, andis scoured as it moves toward the opposite end, from which it is ejectedby the heaters 9 through passage E to chamber E, and is delivered up onthe perforated plate 6-. The dust and broken grain are drawn through theseparating-chamber E to the interior of the case by suction of the fan,and the cleansed grain passes from the machine through passage E. Therefuse drawn through openings 0 and 6* falls upon the inclined plates orshelves M, and the fan sucks the dust therefrom and allows thescreenings to fall into hopper N, having the spout n, which leads out ofthe case.

\V e 'make no claim in this application to the smutter or any of itsparts, as it forms the subject matter of application No. 122,217, filedFebruary 27, 1884, nor to the means for altering the throw of theriddle, as they form the subjectmatter of application No. 122,216, filedFebruary 27, 1884:.
